- The cryo-extract of the flower is 71 times more effective than vitamin E phosphate for cellular differentiation, adhesion and hydration at the epidermal level.
- The thermo-extract of the fruit is 61 times more powerful than vitamin C in increasing collagen I synthesis in the dermal matrix.
- The bio-enzymatic sap extract is 41 times more effective that niacinamide and stabilized vitamin C on epidermal youth parameters (differentiation, adhesion, hydration).
- At a dermal matrix level, the bio-enzymatic extract is 2.51 times more powerful than retinol on collagen I synthesis and 1.51 times more powerful that retinol on hyaluronic acid synthesis.
Rosapeptide’s 4 active ingredients (rose fraction, rose sap and 2 bio-peptides) have been selected for their complementary actions at each stage of collagen synthesis in the skin. Combined in the same complex, their effectiveness on collagen I, an essential protein for skin’s density and elasticity, is increased.
At the skin barrier level,
Rosapeptide significantly strengthens the integrity of the skin barrier1 by stimulating: the synthesis of lipids, the true protectors of the skin against external aggressions, the synthesis of ceramides, which guarantee cohesion in the barrier.
At the epidermal level,
Rosapeptide increases a marker for cellular renewal by +69%1 and multiplies aquaporin 3 activity by 201 for optimum hydration and plumper skin.
Lastly, Rosapeptide increases epidermal thickness, a sign of younger skin, by +19%1,
At the dermal matrix level,
Rosapeptide multiplies collagen I synthesis by 31 for firmer, denser skin.
